A Black Box is a mystery. An enigma. Of course it could contain something nice, but does it? It's the combination of the unknown and anticipation that makes the mind go to places of dread, evil and fear.
This is a park 'n' grab with a short, steep scramble up and down a rocky slope littered with dead branches, followed by a short walk. The Terrain rating was bumped up a bit because of the scramble.
Find the Black Box in the rocks. Find coordinates written inside. Find the final.
The first stage of this cache may be accessible with some snow on the ground. The final is hanging so snow would not be a problem.
Boo! happy Halloween!
